A.R.M.Y is the fandom name for a popular south Korean idol group called BTS, (Bangtan Boys, Bangtan Sonyeondan or Beyond The Scene).
A.R.M.Y (아미) stands for "Adorable Representative M.C for Youth." ARMY means "military" in English. The soldiers in the military always stick together, so it means that the fans (ARMYS) will always be with the Bangtan Boys.

The names for fans of the kpop group BTS. A.R.M.Y. is an acronym for Adorable Representative MC for Youth. Yes, even some A.R.M.Y.s agree the name is kinda stupid. A.R.M.Y.s have a really bad rep because for every loyal fan, there's an argumentative fan that disrespects other groups and starts fanwars.

fake A.R.M.Y. : omo BTS oppas are kings of kpop!!! EXO who? Big Bang who?
good A.R.M.Y. : stfu and be respectful to other groups. You don't need to diss other groups to support BTS.

1. A large body of people organized and trained for land warfare.
2. A tactical and administrative military unit consisting of a headquarters, two or more corps, and auxiliary forces.
3. Where Marines are trained to use Armor, the Air Force and Navy received their start in aviation, and the professional soldiers that not only take and control tactical positions on the modern battlefield, but maintain these positions under severe and adverse conditions.

Often mocked by Marines (bullet sponges), Navy (squids), and Airforce (too many silly names to list). Rivalry is encouraged among the different branches of the military, as a way to buid "espres de corp".

As a side note, the Army trains the only Cavalry Units in the modern US Military, and as any Scout will tell you: "If you ain't CAV, you ain't SHIT".

I joined the Army to learn valuable skills in anticipation of putting myself through college with the Montgomery GI Bill. That's why I learned to drive Bradleys, fire crew-served weapons, call for Arty, and use C4 on bridges.

An often under appreciatted branch of the miltary since the official seperation of the Marines from the Navy. A more stable fighting force then the Marines. Marines strike and go,whereas the Army gains and keeps control of the areas that have been weakened by the military.
